It works!
The correct installation for Python 3 is:

python3 -m venv /tmp/v3
. /tmp/v3/bin/activate
pip install 'setuptools>=19.0.0'
pip install protobuf==3.0.0b2.post2      # needed for Python 3 support for protobuf
pip install Cython                       # needed to build python-trezor
pip install git+https://github.com/trezor/python-trezor.git
pip install git+https://github.com/romanz/trezor-agent.git

Thanks :)

Thanks for reporting this issue!
Could you please try to run it with Python 2?
I think that there may be a problem with Python 3.

romanz avatar romanz commented on June 14, 2024

As far as I understand, this happens due to non-relative import statement at trezorlib/client.py.
In Python 3, it should be written as:

from . import mapping

@romanz How do I do that?

from trezor-agent.

romanz avatar romanz commented on June 14, 2024

Sorry for the inconvenience, I will try to prepare a PR to python-trezor to add support for Python 3.
Meanwhile, you can install Python 2 on your machine, and use it to run trezor-agent...

@romanz Please give it a try and tell me back, branch "python3" might work for you already (basic functionality tested on Python 3.4 against emulator, I don't have device with myself).

romanz avatar romanz commented on June 14, 2024

Thanks a lot for the fixes!
There was a small issue at transport_hid (fixed by trezor/python-trezor#57) and after installing protobuf==3.0.0b2.post2 dependency (since protobuf==2.6.1 isn't compatible with Python 3), trezor-agent works like a charm :)

romanz avatar romanz commented on June 14, 2024

@ywecur trezor-agent should work now on Python 3.
Please try it and tell me if it works for you.

python3 -m venv /tmp/v3
. /tmp/v3/bin/activate
pip install protobuf==3.0.0b2.post2      # needed for Python 3 support for protobuf
pip install Cython                       # needed to build python-trezor
pip install git+https://github.com/trezor/python-trezor.git@python3
pip install git+https://github.com/romanz/trezor-agent.git@python3

trezor-agent -vv localhost               # should print you NIST256 SSH public key

EDIT: this may not work - see below: #11 (comment)

Somehow, the latest hidapi package fails to build on Python3:

However, hidapi==0.7.99.post15 seems to be working fine (on Python 3).

romanz avatar romanz commented on June 14, 2024

@prusnak Could you please take a look on this issue?

from trezor-agent.

slush0 avatar slush0 commented on June 14, 2024

What version of Cython do you use? I had similar issue and fixed it by installing older Cython version. I did not dig into the problem more as I needed to focus to another thing, but if this will fix problem for you, we should stick the version and report it to cython.

Edit: nevermind, I see its installation from pip where cython is not required anymore.

prusnak avatar prusnak commented on June 14, 2024

setuptools is usually the culprit. make sure you have at least version 19.

edit: setuptools>=19.0 added to install_requires

from trezor-agent.

romanz avatar romanz commented on June 14, 2024

Thanks! I will retry the installation :)

from trezor-agent.

romanz avatar romanz commented on June 14, 2024

Now the installation should be even simpler:

python3 -m venv /tmp/v3
. /tmp/v3/bin/activate
pip install -U setuptools Cython
pip install git+https://github.com/romanz/trezor-agent.git

from trezor-agent.

hello, I'm having the same issue as @romanz when trying to install hidapi with python3:
error: unknown file type '.pyx' (from 'hid.pyx')
it works with hidapi==0.7.99.post15, and it fails with any ulterior version.

@prusnak I am running the latest setuptools, see above

prusnak avatar prusnak commented on June 14, 2024

Do you have Cython installed? Preferably also latest

from trezor-agent.

ecdsa avatar ecdsa commented on June 14, 2024

@prusnak I have Cython-0.25.2, installed with pip3
